Blender 2.79. Rendered image show only color and not UV mapped texture
In cycles you need shaders, they determine how the light rays bounce on (or go trhough) the surfaces of an object.

You can't apply textures directly on the material output. (if you notice there are different colors on the sockets. Green can only be connected to green, yellow goes with yellow, purple with purple, and so on). The material output should be connected to shader information only.

In your case you need to connect the color of the image texture to the color input of the diffuse shader, so that the image gets mapped on the faces of the object.
